TLDR
The stability of slopes before and after removal of forest cover was investigated in this article, where Porewater pressures and shear strengths were measured and the soil properties were determined by laboratory and in-house experiments.Abstract:

Impact of plant roots on the resistance of soils to erosion by water: a review
TL;DR: In this article, the authors showed that the decrease in water erosion rates with increasing root mass is also exponential, according to the equation SEP e b RP, where SEP is a soil erosion parameter (e.g., interrill or rill erosion rates relative to erosion rates of bare topsoils without roots), RP is a root parameter, and b is a constant that indicates the effectiveness of the plant roots in reducing soil erosion rates.

Quantifying the mechanical and hydrologic effects of riparian vegetation on streambank stability
TL;DR: In this paper, the authors quantified the effects of vegetation strips on bank stability and highlighted the need to select riparian vegetation strips based on hydrologic as well as mechanical and ecological criteria.

A distributed slope stability model for steep forested basins
Weimin Wu,Roy C. Sidle +1 more
TL;DR: In this paper, a distributed physically based slope stability model (dSLAM) is presented to analyze rapid, shallow landslides and the spatial distribution of safety factor (FS) in steep, forested areas.

Estimating the mechanical effects of riparian vegetation on stream bank stability using a fiber bundle model
Natasha Pollen,Andrew Simon +1 more
TL;DR: In this article, a fiber bundle approach was applied to tensile strength data collected from 12 riparian species and compared the root reinforcement estimates against direct shear tests with root-permeated and non-root-Permeated samples.

The variability of root cohesion as an influence on shallow landslide susceptibility in the Oregon Coast Range
Kevin M. Schmidt,Joshua J. Roering,Jonathan D. Stock,William E. Dietrich,David R. Montgomery,T Schaub +5 more
TL;DR: In this article, it was shown that roots can mechanically reinforce shallow soils in forested landscapes, however, forests can have variations in vegetation species and age which can do damage to shallow soils.

Root strength changes after logging in southeast Alaska
Robert R. Ziemer,D. N. Swanston +1 more
TL;DR: In this article, the role of plant roots in maintaining the shear strength of soi l mantles has been investigated and it was shown that the loss of strength in smaller roots occurs rap idly f o r a l l l spec i e s the f i r s t 2 years.

Effects of Deforestation of Slopes
Colin B. Brown,Maw S. Sheu +1 more
TL;DR: In this article, the root system provides mechanical reinforcement of the soil, vegetation provides a vertical surcharge, wind in trees causes surface shears and moments, and soil moistures content and water level are modified.
